The Java™ Community Process has been updated through JSR 387: Streamline the JCP Program. The most significant change is to open up for Iterative JSRs, i.e. JSRs that intend to deliver multiple releases of a technology on a time-based cadence. The driving force for this change is the 6 month release cadence for Java™ SE.
The first JSR using the option for being iterable is JSR 388: Java™ SE 13 (I guess the JSR name will have to be changed to not include the version number...).
Another change made in this update where changes to reviews and ballots in order to make the process even lighter to accommodate shorter release cycles.
